The Shimano GRX RX827 Di2 1x12 groupset takes gravel riding to a new level of precision and reliability. With perfectly matched shifting and braking components, this system delivers smooth, fast and quiet performance, even on the roughest terrain. Lightweight, durable and designed with attention to detail - everything is focused on maximum control and confidence.
Sophisticated construction and materials
The GRX RX827 groupset uses high-quality materials and smart constructions that deliver an optimal balance between weight and durability. The FC-RX820-1 crankset offers a choice of 40T and 42T chainrings and is available in different crank arm lengths to perfectly suit rider physique. Combined with the DEORE XT M8100 cassette, available in 10-45T and 10-51T, it allows for a wide range that can handle any incline and surface. Thanks to the BEAM SPIDER construction, the cassette is lighter, and shifting action remains tight and direct. The result is a groupset that can withstand intensive use without compromising on efficiency and power.
Extra details and clever finish
The RX827 groupset is not just about the basics but also about the refined finish that makes all the difference on gravel routes. The Di2 Dual Control levers shift wirelessly, respond at lightning speed and are ergonomically designed with a raised brake hood, non-slip coating and ribbed surface for maximum grip. The gravel-specific third button and compatibility with satellite shifters make the cockpit fully customisable to personal preferences. The BR-RX820 calipers give you improved control, with faster engagement and quieter operation, even in tough conditions. Together with the impact recovery system of the RD-RX827 rear derailleur, the groupset is protected from hard hits, and shifting performance remains consistent and reliable.

Compatibility and use
The Shimano GRX RX827 Di2 is designed for 12-speed configurations and uses the MICRO SPLINE hub body. The crankset is available in 170, 172.5 and 175 mm sizes for a precise match with different bikes and riding styles. Cassette options 10-45T and 10-51T, combined with 40T or 42T chainrings, create a versatile system that can handle both long distances and steep climbs. Thanks to flat-mount calipers, integration on modern gravel framesets is clean and simple.
